Framing device for a fire-rated glass floor

Abstract

A framing device for a glass floor unit utilizing a shield connected to the glass floor unit and at least one tab connected to the shield. A threaded member selectively interacts with the tab to adjust the vertical position of the glass floor and to hold down the glass floor relative to a support connected to an edifice foundation.

What is claimed is: 
     
       1. A framing device for a floor structure positioned on foundation, comprising:
 a glass floor unit, said glass floor unit comprising a durable glass portion, including a walking surface, an undersurface, and a side surface located intermediate said walking surface and said undersurface, and a connected fire-rated glass portion, said fire-rated glass portion including a side surface and an undersurface adjacent said side surface; 
 a support for said glass floor unit, said support linked to the foundation; 
 a shield, said shield being fixed to said glass floor unit by a connector for movement of the shield, floor unit, and connector as a whole, said shield being formed of a rigid or semi-rigid material, said shield comprising one part overlying said side surface of said durable glass portion of said glass floor unit and another part overlying said side surface of said fire-rated glass portion and overlying said undersurface of said fire-rated glass portion of said glass floor unit; 
 one tab connected to said shield, said one tab including a tapped opening therethrough; and 
 a threaded member, said threaded member threadingly engaging said tapped opening of said one tab and engaging said support and an adjuster for moving said glass floor unit relative to the foundation, said adjuster comprising said threaded member being turnable relative to said tab and said connected shield. 
 
     
     
       2. The device of  claim 1  which additionally comprises another tab and a mechanism for holding said another tab relative to said support. 
     
     
       3. The device of  claim 1  in which said one tab further comprises an aperture therethrough and said support comprises a tapped opening and said threaded member comprises a first threaded member and further comprises a second threaded member, said second threaded member passing through said aperture and threadingly engaging said tapped opening in said support. 
     
     
       4. The device of  claim 1  in which said shield comprises a first shield and which further comprises a second shield, and said glass floor unit comprises a first glass floor unit and further comprises a second glass floor unit, said second shield being connected to said second glass floor unit in facing configuration relative to said first shield, said another tab being connected to said second shield. 
     
     
       5. The device of  claim 4  in which said one and another tabs are staggered from one another along a dimension of said first and second shields. 
     
     
       6. The device of  claim 1  in which said shield comprises a stainless steel shield. 
     
     
       7. The device of  claim 1  in which said shield comprises a copper shield. 
     
     
       8. The device of  claim 1  in which said connector comprises a mastic layer between said shield and said glass floor unit. 
     
     
       9. The device of  claim 1  in which said one tab connected to said shield is welded to said shield.
